My Buying Guides on Sony Ms Pro Duo
What I Look for Before Buying
When I shop for a Sony MS Pro Duo, I first check whether my device actually supports the format. Since this card is mainly used in older Sony devices like PSPs, cameras, and some handheld gadgets, compatibility is the most important thing for me. I also make sure I know the storage capacity I need, because I do not want to pay extra for space I will never use.
